I have two pairs of these, one dark and one light. I made sense for me, since I was able to get two pairs of goggles for the price of one higher end at the time. I figured it'd be nicer to have cheaper goggles for more light conditions than a great pair at the time, and get better goggles as funds became available.
These goggles actually really surprised me! They fit my face significantly better than my Anon Figments, which fog almost instantly in all but the best conditions. The optics seem to show a bit of distortion on the edges, but it's not terrible. I do however find myself having to lower my whole head to look down, where other goggles (like my buddy's Oakleys) have a better field of view. The frames are also not very substantial; they're pretty thin, and I doubt they'd stand up to a healthy smack. However, I got 23 days out of the two pair, and they still look pretty good, so you probably don't have to worry about longevity unless you abuse your goggles.
However, in the end, you really need to make sure goggles fit your face before buying them. Two pairs of these cost about the same as my single pair of Figments, which I only use as a loaner pair these days since they don't fit me
